The best way to farm ***** is as Thf or with /thf. You start off sneaking up behind the **** and sneak attack it, sneak attack makes sure you end up hitting the **** from behind as hard as you can.

After that just start whacking the ****. Be careful though, the more you whack the **** the more likely to hit you with one of its nasty attacks. The last thing you want while you're face to face with a big **** is to end up

It's from Garrison of the said region, which I believe would make this Cape Terrigan, you obtain the key item from Monsters, and if your country is in control of the region, trade the item to the outpost dudes to start the Event. Once you start garrison your alliance (you want one of this) will be reduced to a certain level and waves of monsters will spawn. There will also be NPCs fighting along side you, your success at the end is determined by how many of those NPCs live.
